Over time, engine bay heat cycles break down the primary and secondary internal copper windings, micro-crack the epoxy potting material, and harden the dielectric silicone boots. This deterioration causes high-voltage secondary arc-through, unmetered energy loss, and spark blow-out under peak manifold boost pressure, manifesting as erratic idle, hesitation, and generic P0300 or cylinder-specific misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit replaces fatigued factory units with high-dielectric reinforced \u003cstrong\u003eUF508\u003c\/strong\u003e-spec coil-on-plug modules paired with Denso Iridium spark plugs. The replacement coils utilize dense magnetic core windings insulated with premium epoxy potting to resist thermal shock and electrical breakdown. Paired with Denso's fine-wire 0.4mm iridium center electrode and ground strap, this setup substantially lowers the required ionization voltage, stabilizing the flame kernel across the combustion chamber. The thermal properties of the iridium alloy resist erosion under continuous boost, ensuring stable ignition timing and restoring OEM drivability.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 Ignition Coils (Replacement for UF508)\u003c\/li\u003e\n  \u003cli\u003e4 Denso Iridium Spark Plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2004-2006 Subaru Baja\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eEJ255 Turbo \/ BT\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e210 hp \/ 235 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eUF508, C760, GN10484, 32009782, 22443AA540, 22433AA640, 22058\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Subaru Baja Turbo 2.5L H4\u003c\/li\u003e\n  \u003cli\u003e2005 Subaru Baja Turbo 2.5L H4\u003c\/li\u003e\n  \u003cli\u003e2006 Subaru Baja Turbo 2.5L H4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the BT Baja?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2004-2006 Subaru Baja equipped with the \u003cstrong\u003eEJ255\u003c\/strong\u003e 2.5L Turbo engine. \u003cstrong\u003eThis kit does not fit naturally aspirated EJ253 non-turbo engines or models utilizing external spark plug wires.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre plug wires included and what are the torque requirements?\u003c\/h4\u003e\n\u003cp\u003eSpark plug wires are not included because this application utilizes direct coil-on-plug technology; plugs must be torqued to factory specifications (15-18 lb-ft) without over-tightening coil mounting bolts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered for the demands of the horizontally opposed boxer turbo platform, this ignition service kit maintains accurate timing and sharp throttle response across all RPM bands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562510713080,"sku":"DS-E8YL10IHZ","price":164.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-subaru-baja-2004-2006-2-5l-1.jpg?v=1790983065","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-subaru-baja-2004-2006-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
